    Dowel Pins

    Precisely align machine parts and prevent movement during assembly. These dowel pins are machined to tight tolerances and have a uniform diameter for a snug fit. They can also be used as a pivot, shaft, or hinge to join moving components. Since dowel pins can be hard to remove, they are best suited for permanent fixtures that don't require frequent adjustments or disassembly.

    High-Strength Alloy Steel—Our strongest, most wear-resistant pins, these won't bend or break from vibration. Use them for high-stress applications, such as mounting and aligning hydraulic cylinders and injection molds. They perform best in dry environments since moisture will cause them to rust.

    Corrosion-Resistant Stainless Steel
    Image of Product. Front orientation. Dowel Pins. Standard Tolerance, Plain Head.
    18-8 Stainless Steel—The choice for wet and outdoor environments. In addition to resisting rust, these pins also withstand mild chemicals such as cleaners and degreasers. They are strong enough to join most components but won't withstand extreme stress and vibration as well as steel.
    Highly-Corrosion-Resistant 316 Stainless Steel—Our most corrosion-resistant pins, these hold up in just about any environment. They won't degrade from exposure to weather, salt water, and most chemicals. Like 18-8 stainless steel, they're strong enough to join most components but won't withstand stress and vibration as well as steel.

    Captive Pins

    Image of Product. Front orientation. Captive Pins.
    Also known as pilot pins, use these pins to position, pivot, and align components. To install, punch or drill a hole in sheet metal, then use a punch and anvil or arbor press to clinch the head to the metal.
    Pins are passivated for added protection against corrosion and oxidation. The ends are chamfered for easy insertion.
    MPP PEM® Series—MPP PEM® Series pins work with most materials. Made of A286 stainless steel, they're our strongest captive pins, with corrosion resistance comparable to 18-8 stainless steel pins. They are nonmagnetic.

    Undersized Dowel Pins

    You don’t need to create precise holes for these pins when aligning parts you plan to bolt together. They have a slightly undersized diameter to slip into place without the need for special installation tools, like an arbor press. Undersized pins are also used for prototyping and positioning components you need to assemble and disassemble frequently.

    Squeeze these pins into holes and they expand slightly, creating tension to hold parts in place. They are often used as hinge pins and as fasteners for springs and power transmission components. An alternative to dowel pins, they're lighter in weight with a hollow center and don’t need a precise hole. Also known as roll pins.
    Spring Steel—These pins won't deform from stress and vibration. Although they're stronger than stainless steel, they're best for dry environments since moisture will cause them to rust.
    Corrosion-Resistant 18-8 Stainless Steel—The choice for wet and outdoor environments, these pins resist rusting. They are strong enough to join most components but won't withstand extreme stress and vibration as well as steel.

    The best spring pins for joining parts exposed to vibration and shock. They're often used in power transmission, automation, and other assemblies with constant motion and sudden starts and stops. Because of their spiral shape, they flex to conform to holes that aren’t perfectly round.
